T ALL WHOM IT MAY CONCERN:

Be it known that I, CHARLES R. WEBB, of the cityot` Philadelphia, in the county of Philadelphia, and

State of Pennsylvania, have invented a new and useful Device for Preventing the Ends of the Jaws from Chafing a Vessels Saddle; and I do hereby declare that the following is a full, clear, and exact description of the coustruction of `the same, reference being had to the annexed drawings, and tothe letters of reference marked thereon, making part of this specifieation,in which-l Figure 1 is a perspective view ofthe device as applied.

Figure 2,'an end elevation in partial section, and

4Figure 3 a sideelevation'in partial section,and

Figure 4 a ground plan. l

When a vessel having a heavy boom has a still` breeze, the jaw on the Windward side of the mast-is raised, and the low-cr corner of the leeward jaw is pressed against the saddle, wearing away both saddle andjaw.

The interposition of the saddle-slides, herein described, efi'eetually prevents the abrasion of either saddle or jaw, as one or both slides always present a flat surface to the saddle, thereby preventing the jaws from coming in contact with the saddle. l

A is the slide, eensisting substantially of a flat surface, which is presented to the uppersi'de of the-saddle E, a part of said slide being Fitted for the receptionl ofthe bolt B.

B, figs. 2 and 3, is .a bolt, firmly fastened in the jaw C, by means of the nut and washers F F', and the shoulder D, iig. 2. The bolt B has an oblong head, on which hangs the slide A. The head of said holt allows the slide A to adapt itself to the upper side of the saddle E, in whatever position'the jaws may be placed, by the shifting ofthe sail, but prevents it from deviating from its proper course on the saddle.

What I claim as my invention, and desire to sec-ure by Letters Patent, isl The slides A A', or their equivalents, interposed and properly secured between a vessels saddle, E, and

I the forward ends of the jaws C C', for the purpose of preventing the jaws from chafing the saddle, substantially as herein described and for the purposes set forth.
